IMPROVEMENT IN STEAM-GENERATORS.

Specification forming part of Letters Patent No. 59, [46, dated October23, 1866.

To all 'whom it may concern.'

Be it known that we, JAMES WOODFORD and WILLIAM H. BAYGROFT, ofPortland, in the county of Dodge and State of Wisconsin, have invented.a newand useful Improvement in Steam-Boilers; and we do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the annexed drawings, making part of thisspecification, in which- Figurc'l is a perspective view. Fig. 2 is aView of the end piece. Fig. 3 is a horizontal section, and Fig. 4i is avertical cross-section.

The same letters are used in the several iigures in indicating identicalparts.

'Our boiler is constructed with especial reference to the use ofhydrocarbon oils as a fuel for generating steam 5 but the mode adoptedof increasing the fire-surface is applicable,

- with slight modifica-tions, to all kinds of fuel.

The following description will enable persons skilled in the art toconstruct the same.

A is a lamp for containing the oil used as fuel. B is the wick-tube,extending the entire length of the boiler, and B wheels by which theheight of the wick is regulated in the ordinary manner.

D is the boiler, which is cylindrical on its exterior surface. It isconstructed with an internal fire-chamber, F, extending through theentire length ot the boiler, through which the flame passes into theflues F1, which lead into the internal flue, F2, the smoke escaping'through the smoke-stack G.

The boiler being set in the usual manner, the

heat will be applied to the lower surface as well as on both faces ofthe fire-chamber F, and on the surfaces of the fines F1, and also aroundthe internal flue, F2, extending the entire length of the boiler, ornearly so.

The water will fill the spaces E and also the space E and cover the topofthe flue F2.

By this means a very large area of fire-surface is exposed to the water.

The plates H t into and close the ends of the fire-chamber F.

C is a jacket surrounding vthe wick-tube. The cold water entering at C2passes entirely around the tubes B, and is heated in its passage beforebeing drawn out through the pipe O1. By this means we are enabled tofeed the boilerwith hot water.

The hood I, setting over the jacket C, directs a current of air againstthe base of the flame.

What we claim as our invention, and desire to secure by Letters Patent,is-

1. A boiler, D, when constructed with an internal {ire-chamber, F, uesF1, and an in ternal flue, F2, and arranged substantially as set forth.

. 2. In combination with a boiler, D, a jacket, C, surrounding thewick-tube B, for heating the water before it is applied to the boiler,substantially in the manner set forth.
